ticularly to the constructionof the hulls.

thereof.

One of the objects of the mvention is to so construct the for'ebody of the hull .of the vessel thatl it is adapted to cleave the water as it advances and at the same time leave,

as `far as possible, undisturbed lthe. water over which its'midship portionl has to pass.

Another object of the invention is to so shape the hull that the amou'nt of its submerged surface,

16 by its speed is increased. v

A further objectfof the invention is to provide the' hull with compartments or bulkheads which serve at the same time as bai.

lasting devices, designed to steady and trlm the' vessel, and also to prevent careening,

- rolling, pitching, etc.A

A still further object of theinvention is to so shape the bottom of the vessel that the propellers and rudder thereof receive at all times afree' and solid flow of water'for their 'eiiicient operation.

' With these' and other Objects in view, which will more full appear as the nature of the invention is ao! same' c onsists in .the combination, arrangement-and construction of parts 'hereinafter l described, pointed out in theappended claims and illustrated in the accompanying drawings, lit being understood that many changes may -be made vin the size and proportion of the several' parts and details of constructionfwithin the scope of the ap= pended claims, without' departing -rom the' 'spirit or sacrificing any of the' advantages of the invention.

One of the many possible embodiments of the invention is illustrteg in the accomanymg' drawings, in w ic Y p Figure 1 is a sheer plan of a hull constructed in accordance with the present invention;\F ig. 2 is a bottom plan view thereof; Figs. 3 tov10 inclusive, vare sections taken on Fig', each section being taken on aline thereof which is indicated by numerals ofreference corresponding to thenumeral of ts respective figure' and Fig. 11 `is a body lan o the hull.l 2

PThebow12ofthehullhasasha1-pcutwater 13, the sides 14 of the bow, more par- 0r in other words its draft is reduced to a possible minimum, where-` 1 ings, the bottom rises gradually toward the stern and is gradually curved transversely,

tter understood, thev vdivided transversely into a greatest width of beam 15 in the forebody of the vessel. From this point the sides con'- verge -along gentleostream lines toward the stern16, which is rounded as shown in Fig.

2 of the drawings. The 'mi'dship body-17 of the hull, extending from the plane indicated bg the section line 5 -5 to approximately t e plane indicated by the section line 9 9, I

-indicated in Fig. 1 of the drawings, has sub' startally' vertical sides .18 and a flat bottom 19. Atv or about the plane indicated by the section'linel 9-9 in Fig. v1 ofthe drawy see for instance Fig. 10 'of the drawings.

In the forebody the bottom is constructed 4 as a downwardly directed wedge, the apex of which appears most prominent at 20. This apex is gradually drawn up or fiat. tened out as it passes aft, as shown in Figs.

3 and 4:, andat or about the plane 5-#5 merges into a flattened portion 21 (Fig. 5),

which is disposed asubstantial distance be. low the bottom portion 19 of the hull proper.

'ship body of the hull and for some distance in the orebody, the width of thev bulkhead bottom expanding gradually along ne lines from'n the section line 4-4 to amidship and thence gradually decreasing to the plane` indicated by the section line 9 9. The

greatest width of the bulkhead bottom exceeds considerably that of the of beam, as clearly shown inI ig. 2 of the drawings The bulkhead structure may be plurality of The flattened portion 21 rises from forward eatest width water-tight com artments which may bel used as| coal bun PUTP ers` and for other storage OSes',- and also -engine rooms. The sides of the bulkhead structure, denoted by the' numeral 23, are curved outwards romtlie Y sides 18 of the hull and then downwards, as shown at 24, joiningthe bottom ofthe bullthead structure The bottom f the blkhead ammira 'isV flat inthe .plane 5-45, as indicated above, and thence longitudinally out gradually Iuntil it joins the stern at the plane 9 9. The depth of the recess decreases thus gradually, as it proceeds aft.

The hull is provided with twopropellers 25, the'shafts 26 of which are driven by en'- gines disposed in the bulkhead structure.

These propellers are located below the ris-l ing bottom portion of the hull in the afterbody and in line with the longitudinal recess in the bottom portion of the bulkhead structure, thereby receivingr continuously a free and solid flow of water for their efficient operation. Inasmuch as these propellers are disposed a considerable distance forward of the stern -of the vessel, they will be fully submerged under all conditions'of lading and in all kinds of Weather.

It will be Aobserved. that the forward Wedge-shaped portion of the vessel iscomparatively slender, thereby producing a reduced bow wave, which is thrown further aft than usual, and dividing the water so that the ship tends to go through without rising. Coming to the midship portion, the water divided by the Wedge passes, guided by the sides 23 of the bulkhead structure, to either side, and comparatively undisturbed water is left, over which the recessed bottom of the bulkhead structure can glide. The bulkhead structure, by reason of its width compared with that of the hull proper, serves as a ballastingdevice projecting from the vessel sides laterally, thereby forming .a

resistance surface to prevent careening or capslzing vand also to enable the vessel to point or sail closer to the wind and `to prevent making leeway. The bulkhead structure, at the same time,`prevents rolling and pitching in addition to .its normal function, that is to say in addition to litsproviding water-tight compartments. Furthermore, the bulkhead structure, by reason of its width, decreases considerably the draft of the vessel, thus effectively increasing its speed when movingthrough the water. Inasmuch as the bottom of the bulkhead structure rises gradually from its point of commencement as it passes aft, fthe vessel has no tendency to rise at the bow. Pitching isthus to a great extend prevented.

What I claim is:-

1. A marine vessel comprising a hull, and a longitudinal laterally extending exterior bulkhead structure thereon. surrounding the bottom and -part of the sides of said hull, said bulkhead structure having a bottom rising from its bow I end to its stern end, said bottom being shaped to provide a longitudinal and inwardly extending recess. f

2. In`a marine vessel according toclaim I, the bottom of said bulkhead structure merging into the bottoml region of the bow por# tion and thebottom regionof the stern portion of said hull.

3. Ina marine vessel according to claim l, the bottom of said hull being substantially flat throughoutthe midship body.

4. In a marine vessel according to claim 1, said bulkhead structure extending over part of the bowl portion and the midshipbody of said hull.

Signed at New York, in the county of New York, and State of New York, this 9th day of December, A. D. 1925.
